Mine, All Mine

There's this girl Oh, I love her so much She already knows But, unfortunately, I lost my chance Now there's this new 'partner' Hates my guts But they don't know what me and her share Everyday, I establish my presence We call every night I make her laugh, giggle, and smile All of it is so worth it We even flirt And that's where I wonder Who's is she? Is she theirs? Or mine? Mine, all mine I put far more effort in And make her happier I just know Maybe if I try a little harder She will be mine Mine, all mine
